CARBURETOR ADJUSTMENT
The carburetor has been carefully adjusted at the factory and should
not require any further adjustment. Only the idling speed can be
adjusted by turning the idle speed adjustment screw (see sketch).
The correct speed is 2700-3300RPM (or just below the clutch
engagement speed).
Turning the adjustment screw clockwise will increase the idle speed.
If further adjustment is necessary, please contact a local authorized
MARUYAMA dealer.
OPERATING THE BRUSHCUTTER
MARUYAMA brushcutters are designed and tested to cut nearly all grasses, thick weeds and brush. As you
continue to use the equipment, many tasks will become easier.
CAUTION-Read the SAFETY INSTRUCTIONS concerning the proper use of the brushcutter on page US-1.
CAUTION-Observe all warnings that appear on the brushcutter.
CAUTION-Use only the correct blade approved for the task and the machine.
CAUTION- Always use the Shoulder Strap when operating a brushcutter with a metal blade.
The brushcutter must be positioned to the right side of the operator when used with a metal
blade.
CAUTION- Always make certain the blade is installed to rotate in the proper direction and that all holding and
fastening parts are correctly secured.
CAUTION-Remove the holding tool (4mm hex wrench) before operating the equipment!
CAUTION- Do not continue to use a blade that is dull, damaged, or that vibrates during use. Whenever a
cutting blade becomes clogged with debris, immediately stop the machine and clean the blade.
CAUTION- When cutting heavy brush or small trees, use the proper method to avoid dangerous "KICK-
BACK" (see sketch).
No Kick-back Zone
REGULAR MAINTENANCE
AIR FILTER
The air filter should be cleaned each time the brushcutter is
used. (Or more often with extreme conditions.)
Remove the filter cover and take out the foam element. Wash
the foam element in kerosene or warm detergent, then
squeeze it dry. Apply oil (#30 wt.) to foam element , removing
all excess oil. Assemble and reinstall the foam element and
filter cover.
